Cosmologists at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory are experimenting with a prototype radio telescope, called the Baryon Mapping Experiment (BMX). Built at the Lab in 2017, the prototype serves as a testbed for managing radio interference and developing calibration techniques. Lessons learned from the prototype could pave the way for Brookhaven to develop a much larger radio telescope in collaboration with other national Labs, universities, and international partners.

Even as the Dark Energy Spectroscopic Instrument, or DESI, lies dormant within a telescope dome on a mountaintop in Arizona, due to the COVID-19 pandemic, the DESI project has moved forward in reaching the final formal approval milestone prior to startup.

Despite a temporary shutdown of the Dark Energy Spectroscopic Instrument in Arizona – which was in its final stages of testing in preparation to begin mapping millions of galaxies in 3D when the pandemic struck – a variety of project tasks are still moving forward.

Connecting the dots in the sky could shed new light on dark matter

January 13, 2020 sarah Jonas 0 Comments Dark Energy, Dark Energy Survey, dark matter, Slac, SLAC National Accelerator Laboratory

Astrophysicists have come a step closer to understanding the origin of a faint glow of gamma rays covering the night sky. They found that this light is brighter in regions that contain a lot of matter and dimmer where matter is sparser – a correlation that could help them narrow down the properties of exotic astrophysical objects and invisible dark matter.

How to Build a 3D Map of the Universe – and Why

December 6, 2019 sarah Jonas 0 Comments Dark Energy, dark matter, Physics, Physics & Astronomy, Supernova

In the 1980s, Saul Perlmutter at the Department of Energy’s (DOE) Lawrence Berkeley National Laboratory (LBNL) and his collaborators realized that they could use data about supernovae to research the history of the universe. They expected to see that very distant supernovae appear a bit brighter than they would in an expanding universe that wasn’t slowing in its growth.

The data revealed something else entirely.
